Depth of Field Focus & Depth of Field m The range of distances in front of and behind the plane of focus that appears acceptably sharp in the final image. DoF ≈ 2u²Nc / f²

Depth of Field Preview Cameras, Formats & Systems A control that stops the lens down to the working aperture so the actual depth of field can be seen before exposure.

Depth of Field Scale Focus & Depth of Field m / ft Markings on a lens barrel showing the near and far limits of sharpness for each aperture at the set focus distance.

Deep Depth of Field Focus & Depth of Field m A wide zone of sharpness in which foreground, subject and background all hold detail.

Depth of Focus Focus & Depth of Field µm The tolerance in sensor position, on the camera side of the lens, within which the image stays acceptably sharp. ≈ 2Nc

Diffraction Limit Optics, Lenses & Filters f-stops The aperture beyond which diffraction, rather than lens design or sensor resolution, becomes the factor limiting sharpness. N_limit ≈ pixel pitch / 1.22λ

Diffraction Optics, Lenses & Filters µm The spreading of light waves as they pass the edge of an aperture, which softens the image at small f-numbers. d = 2.44 × λ × N
